DISK HARROW.

SPECIFICATION forming part of Letters Patent NO. 623,677, dated April 25p, 1899.

Application filed September 15, 1897. Serial No. 651,728. (No model.)

To all whom, t may concern:

Beit known that I, MOSES IV. KOUNs, a citizen of the United States, residing at Bellevue, in the county of Huron and State of Ohio, have invented certain new and useful Improvements in Disk I-Iarrows,of which the following .is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in disk harrows. On the 13th day of April, 1897, I patented improvements in this class of machines, as seen by Letters Patent of the United States numbered 580,408. That patent relates, essentially, to an auxiliary disk combined with the forward and rear gangs ofdisks in such wise as to travel, essentially, within the area covered by the two innermost disks of the forward gang for the purposes specied in such patent, such auxiliary disk being attached to the forward gang. My present improvements relate to auxiliary disks carried by the gangframes and arranged to work conjoi'ntly with the outer disk of each gang, so as to level off the soil thrown up by such outer disks.

In the accompanying drawings, on which like reference-letters indicate corresponding parts, Figure l is a perspective View of my disk harrow entire. Fig. 2 is a plan view of the same with the auxiliary disk adjusted away from the inner disk of the rear gang; Fig. 3, a similar view with such disk adjusted near to such inner disk; Fig. 4, a detail end View of the forward gang, showing the auxiliary disk in side elevation and the lever-pitman connecting with the gang-frame; and Fig. 5, a detail view showing the adjustable connection between one of the standards and the bar of the central auxiliary disk.

A general frame is composed of a central casting A, `hounds B, connected to it, and bars C, also connected to it and carrying end blocks D. A seat E has its standard secured to this central casting, and in practice a pole is suitably connected with the hounds B. Toothed segments F are secured to these hounds, and hand-levers G are vmounted on the hounds and have their detents g adapted'to engage with these segments to lock the levers in different positions. To these levers are connected pitmen H and I, respectively, the other ends of such pitmen connecting with the gang-frames in such manner that when the levers are manipulated the gang-frames are adjusted on their pivots, so as to occupy a more or less oblique position relatively to the line of travel. These gang-frames are composed of forward and rear bars J and K, connected by standards L, whose lower ends form bearings for the shafts M of the disk gangs, the disks O being strung upon such shafts and properly spaced by thimbles or sleeves Q. The manner of connecting these disk gangs with the main frame consists in employing a plate R, secured to the gang-frames and having pillars S, capped by a strap T, and arbolt U, passing through the strap, the block D, and into the plate R, such bolt forming the pivot-piece for the gangs. Thus it will be seen that when the levers and pitmen are used to manipulate the gangs they will turn on ytheir pivots U.

Referring now more specifically to the auxiliary disks, I will iirst refer to the central auxiliary disk shown at V and having a studshaft W, mounted in a bracket X, secured to a bar Y, attached at Z to the standard L. The connection Z is adjustable, as seen in Fig. 5, so that the auxiliary disk V can be adjusted up and down to travel at different depths in the soil. Serrated plates a and Z9, as shown, are used for this purpose. The serrated surface c on the block X and the serrated plate d and a bolt e permit the adjustment of the auxiliary disk V to different positions with respect to the line of travel, so that it may be placed more or less oblique to such line.

The letter f designates a bar fitted to aserrated plate h, adapted to engage with a serrated block z', which block, plate, and bar are held to an extended part Z of the bar J of the gang-frames. The rear end of this bar fearries a stud-shaft m, connected with the outer auxiliary disk 0, the arrangement permitting such disk to revolve. The position of this outer auxiliary disk has relation to the outer disk of each gang, being in the rear of it and more or less near its path, in such wise that it will take up the soil which has been thrown IOO into ridge form by thc outer disk of the gang and level it off, and thus prevent leaving in the field a ridge along Where the outer disks travel, but instead thereof a smooth and properly-cultivated surface. These outer auxiliary disks are to be adjusted to run at varying depths, as shown by the serrated plates 7L and blocks t'. Thus with my improved harrow there is no ridge left either between the inner disks of the gangs or outside of the outer disks of the gangs. These outer auxiliary disks are reversed in position compared with the outer disks of the gangs.

In showing the entire machine in Fig. l I have illustrated a scraper for the disks, composed, essentially, of bars A and Scrapers proper B', with a foot-piece C to actuate the scraper in one direction and a spring D' to actuate it in the other direction. These features form no part of the present invention.

Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is

l. In a disk harrow, the combination with a disk gang, of an outer auxiliary disk connected to such gang and trailing in the rear thereof and turned with its concave side t0- ward the outer disk of such gang.

2. In a disk harrow, the combination with a disk gang, of an auxiliary disk secured to such gang and trailing in the rear of its outer disk with its concave side turned toward the outer disk of said gang and adjustable to run at different depths in the soil.

In adisk harrow, the combination with two disk gangs, ot' a central auxiliary disk and outer auxiliary disks, theformer being attached to one gang and trailing between its two innermost disks, and a lever connected up to adjust such gang and disk to place the disk near to or farther from the inner disk of the other gang, and such outer auxiliary disks connected to the gangs, trailing behind their outer disks, and reversely turned to them.

In testimony whereof I aflix my signature in presence of two witnesses.
